An eccrine angiomatous hamartoma with histopathological features of a papillary haemangioma in a neonate

Abstract

Eccrine angiomatous hamartoma (EAH) is a benign hamartomatous tumour characterized by a combination of proliferative eccrine and vascular elements. Papillary haemangioma (PH) is a distinct cutaneous haemangioma with predominantly intravascular capillary proliferation within dilated thin-walled blood vessels. EAHs have been reported in combination with various vascular components. We present the first case in the dermatological literature, to our knowledge, of a patient with congenital EAH with the histopathological features of a PH.
